What does it look like?

Alcohol: Risky business
Let's not forget about the rampant use -- and abuse -- of alcohol among Canadian teens. A 2001 survey of Alberta adolescents aged 12 to 18 found that 65 per cent had consumed alcohol at least once in the previous month. Almost half -- 46 per cent -- said they had consumed five or more drinks in a row during the same time.

Alcohol can pave the way for sexual assault and is also associated with increased risk of accidental injury and death, including alcohol poisoning and suicide. Over the long term, heavy drinking can cause brain and nerve damage; high blood pressure and stroke; liver disease; diseases of the stomach, digestive system and pancreas; breast and throat cancer; low sex-hormone levels; and alcohol dependence.
